Making a stopwatch function

#The first part of this works fine a period prints every 15 seconds (ping –c 3, takes 2 seconds). However no “Minutes since start = “ message prints.

#By all rights it should print 2 times once when it is outputted from “grep” and a second time when cat reads it. I would use cron but I am not sure how to make cron work the way I need it to for this program, I need a stopwatch that notifies every 60 seconds, 5 minutes, 20 minutes etc…

#I know this is a roundabout method but I am still pretty new to UNIX so go easy on me. Other methods of doing this would be great but I would really appreciate help getting this to work as it would give me a better understanding.

#The script is as follows..

:

Code:

# Contained test of principal
#
cnt=0
while [ $cnt -lt 600 ]
 do
    while [ $cnt -lt 300 ]
     do
      echo .
      ping -c 3 not_connected_IP>>/tmp/pinglog$$.txt
      sleep 13
      ((cnt=cnt+15))
     done

    while [ $cnt -lt 300 ]
     do
      echo -n "Minutes since start = " > divres
      echo "scale=2; $cnt/60" | bc >> divres
      if cat divres | grep .00
       then
        echo
        cat divres
      fi
     done
 done
rm -r /tmp/pinglog$$.txt
